To determine the relationship between N-terminal pro-brain-type natriuretic peptide (NT-proBNP) and angiographic no-reflow phenomenon in patients with acute myocardial infarction (AMI) after primary percutaneous coronary intervention (PCI).


The data of 106 consecutive AMI patients undergoing primary PCl were collected and analyzed retrospectively. NT-proBNP was obtained pre-PCI at admission. According to the NT-proBNP level, they were divided into normal and elevated NT-proBNP groups. The no-reflow phenomenon was defined as an angiographic outcome of Thrombolysis In Myocardial Infarction (TIMI) grade < 3 without accompanying mechanical factors.


The patients with elevated NT-proBNP on admission had a higher incidence of no-reflow phenomenon than those with NT-proBNP level. Compared to normal reflow counterparts, no-reflow patients had a higher NT-proBNP level [1883 ng/L (484 ∼ 5500 ng/L) vs 220 ng/L (87 ∼ 926 ng/L) P = 0.046]. Multivariate analysis showed that a high NT-proBNP level (NT-proBNP > 1765 ng/L) on admission was an independent predictor of no-reflow. This cut-off value yielded a sensitivity of 60.0% and a specificity of 87.5% respectively.


The NT-proBNP level on admission may be a prognostic biomarker in the prediction of the development of angiographic "no-reflow" phenomenon after primary PCI for AMI patients.
